Minimalist linkers suitable for irreversible inhibitors in simultaneous proteome profiling, live-cell imaging and drug screening

Activity-based protein profiling (ABPP) and bioimaging have been powerful approaches for in situ drug screening and target identification. However, these approaches are still hindered by the preparation of high-quality probes. To address this challenge, we developed a series of novel minimalist linkers for irreversible inhibitors by incorporation of various bioorthogonal handles into an α,β-unsaturated amide, a common moiety of many irreversible inhibitors. The linker-containing probes have been demonstrated to be suitable for simultaneous protein labelling, live cell imaging and drug screening.

4 - (Substituted phenylamino) aminoquin oxazolines, preparation method and application thereof

The invention specifically relates to novel 4-(substituted phenylamino)quinazoline compounds with antineoplastic activity and a preparation method thereof, belonging to the field of pharmaceutical chemical engineering. The 4-(substituted phenylamino)quinazoline compounds have an effective irreversible inhibiting effect on tyrosine kinase and/or good in-vivo pharmacokinetic behavior and are an effective tyrosine kinase irreversible inhibitor.
